Just to avoid confusion, as the 84mm Carl Gustav also had a TPTP round, the round for the 106 RCL was actually called Cartridge QF 106mm, but to avoid confusion with the American training round, which was similar to HEP and not in Australian service, it was simply called TPT Projectile .
The Australian made round having a tracer element whereas the American practice round did not.
